Each wing of the museum's three exhibition floors is anchored by a landmark object—a large, significant artifact that highlights the theme of that wing. Landmark objects include the John Bull locomotive, the 1865 Vassar Telescope, the Greensboro lunch counter, George Washington Statue, a Red Cross ambulance and a Dumbo ride car.
Artifact walls consisting of 275 feet (84 m) of glass-fronted cases line the first and second floor center core. The artifact walls are organized around themes including: arts; popular culture; business, work and economy; home and family; community; land and natural resources; peopling American; politics and reform; science; medicine; technology; and America's role in the world.
